Jess J. Karch, Sr., appeals the judgment of the Sarpy County District Court, which affirmed the county court’s refusal to dismiss two misdemeanor counts upon the claim that Karch was not brought to trial within 6 months, as required by Nebraska’s speedy trial act, Neb. Rev. Stat. § 29-1205 et seq. (Reissue 1995). For the reasons stated below, we affirm the judgment of the district court.
BACKGROUND
On April 12, 2000, the State filed a criminal complaint under case No. CR00-1966, charging Karch with two felony counts: *232 count I, second degree assault, a Class III A felony; and count II, child abuse, a Class III felony. Both charges were alleged to have occurred at a specific address in Sarpy County on or about March 18, 2000. Karch appeared on June 6 at the initial hearing before the county court, at which time the court scheduled a preliminary hearing on both charges for June 29.
With leave of the court, the State filed an amended criminal complaint on June 29, 2000, charging Karch with four misdemeanor counts: count I, third degree assault, a Class I misdemeanor; count II, third degree assault, a Class I misdemeanor; count III, disturbing the peace, a Class III misdemeanor; and count IV, interfering with a public service company, a Class II misdemeanor. All of the amended misdemeanor charges were alleged to have occurred in the same place and on the same date as the original felony charges.
Karch pled not guilty to the four amended counts at the arraignment in county court, and the court set the matter for pretrial conference. On August 2, 2000, Karch waived his right to a jury trial, and the matter was set for bench trial on September 11. On September 11, the date of Karch’s scheduled trial, the court denied the State’s motion for continuance; the court subsequently granted the State’s request to dismiss without prejudice.
The State refiled a criminal complaint against Karch on September 14, 2000, under case No. CR00-4836, charging him with the same four misdemeanor counts charged in the amended complaint of June 29. Karch appeared before the county court on October 24, pled not guilty to all four counts, and posted bond; the court scheduled a jury trial to begin on October 26.
On October 25, 2000, Karch filed a motion to discharge all counts against him, pursuant to his constitutional and statutory right to a speedy trial. The court scheduled a hearing on Karch’s motion for November 2. At that hearing, the county court took judicial notice of the pleadings and filings concerning cases Nos. CR00-1966 and CR00-4836. Karch argued that the filing date for all four charged offenses from case No. CR00-4836 should relate back to April 12, 2000, the date of the original felony complaint filed in county court at case No. CR00-1966. Karch argued, based on this court’s decision in
State
v.
Sumstine,
Karch appealed the county court’s refusal to dismiss counts III and IV to the district court. After a hearing, the district court entered an order affirming the county court’s refusal to dismiss counts III and IV and remanded the case to county court for trial. Karch appealed, and pursuant to our authority to regulate the caseloads of the appellate courts, we moved this appeal to our docket.
ASSIGNMENTS OF ERROR
Karch assigns, restated, that the district court erred in affirming the county court’s (1) refusal to relate the date of filing of counts III and IV, for computation of speedy trial time, back to April 12, 2000, the date of the original complaint charging Karch with two felonies, and (2) refusal to dismiss counts III and IV. We consolidate these errors for purposes of our analysis.
STANDARD OF REVIEW
Generally, a trial court’s determination as to whether charges should be dismissed on speedy trial grounds is a factual question which will be affirmed on appeal unless clearly erroneous.
State
v.
French,
To the extent an appeal calls for statutory interpretation or presents questions of law, an appellate court must reach an independent conclusion irrespective of the determination made by the court below.

ANALYSIS
Nebraska’s speedy trial act, § 29-1205 et seq., provides in part that “[e]very person indicted or informed against for any offense *234 shall be brought to trial within six months, and such time shall be computed as provided in this section.” § 29-1207(1). Karch argues that he should have been brought to trial within 6 months of the filing of the April 12, 2000, felony complaint and, because he was not brought to trial within that time period, counts III and IV should have been dismissed.
Where a felony offense is involved, the 6-month speedy trial period commences to run from the date the indictment is returned or the information filed, and not from the time the complaint is filed.
State
v. Trammell,
The constitutional right to a speedy trial is guaranteed by U.S. Const, amend. VI and Neb. Const, art. I, § 11; the constitutional right to a speedy trial and the statutory implementation of that right exist independently of each other. State v. Tucker, supra. See, also, State v. Born, supra. In Born, we noted that the Legislature did not specifically address the problem of setting statutory time limits for procedures in felony cases prior to the return of an indictment or the filing of an information. We stated, however, that we would consider unreasonable delay occurring in the prosecution of felony offenses prior to the return of an indictment or filing of an information in determining whether the defendant was denied the constitutional right to a speedy trial. Id.
Karch has waived any constitutional speedy trial claim. Although he cited both his statutory and his constitutional rights to a speedy trial in his motion to discharge, Karch did not assign or argue his constitutional right to a speedy trial in his brief. An appellate court does not review questions concerning a defendant’s constitutional right to a speedy trial when those questions are not raised in both the trial court and the appellate court. See
State v. Kearns,
Karch’s statutory speedy trial claim also fails under our recent decision in
State
v.
French,
Here, we must consider whether the amended complaint filed against Karch on June 29,2000, supersedes the original complaint filed on April 12, 2000. The April 12 complaint charged Karch with one felony count of second degree assault and one felony count of child abuse. The June 29 amended complaint charged Karch with counts I and n, both third degree assault, count III, disturbing the peace, and count IV, interfering with a public service company; all four counts were misdemeanor offenses. Counts I and II of the June 29 complaint were dismissed by the county court on speedy trial grounds. The remaining counts III *236 and IV, however, do not relate back to the original felony complaint, as count III, disturbing the peace, and count IV, interfering with a public service company, are completely different crimes than those alleged in the original complaint. Thus, under State v. French, supra, the June 29 complaint superseded the April 12 complaint and the April 12 complaint ceased to perform any office as a pleading as of June 29.
Although the speedy trial act expressly refers to indictments and informations, it is well settled that the act also applies to prosecutions on complaint in the county court.
State v. Vrtiska,
Karch filed his motion to discharge on October 25, 2000; thus, the State has not exceeded the 6-month time period in bringing Karch to trial on the crimes charged in the June 29 amended complaint. Karch’s speedy trial claim fails, and upon entry of the mandate from this appeal, the State will have 67 days in which to bring Karch to trial on counts III and IV.
*237 CONCLUSION
For the reasons set forth above, Karch’s assignments of error are without merit and his statutory right to a speedy trial was not violated. We affirm the judgment of the district court.
Affirmed.
